I know he's busy writing Detective Comics and Countdown and, I think, still working on "Lost," but he speaks very highly of his time at "Ewoks." I was going over some old Insiders, and in the article about the cartoons, he said some very sensible things that make me think he'd be a great story editor for this. And, of course, his work on Batman: The Animated Series speaks for itself.
Even if it's just bringing him on board as a consultant for a week a year, I'd feel a bit better about this.
